Vehicle Accident Analysis and Reconstruction Methods

In this third edition of Vehicle Accident Analysis & Reconstruction Methods, Raymond M. Brach and R. Matthew Brach have expanded and updated their essential work for professionals in the field of accident reconstruction. Most accidents can be reconstructed effectively using of calculations and investigative and experimental data: the authors present the latest scientific, engineering, and mathematical reconstruction methods, providing a firm scientific foundation for practitioners. Accidents that cannot be reconstructed using the methods in this book are rare. In recent decades, the field of crash reconstruction has been transformed through the use of technology. The advent of event data records (EDRs) on vehicles signaled the era of modern crash reconstruction, which utilizes the same physical evidence that was previously available as well as electronic data that are measured/captured before, during, and after the collision. There is increased demand for more professional and accurate reconstruction as more crash data is available from vehicle sensors. The third edition of this essential work includes a new chapter on the use of EDRs as well as examples using EDR data in accident reconstruction. Early chapters feature foundational material that is necessary for the understanding of vehicle collisions and vehicle motion; later chapters present applications of the methods and include example reconstructions. As a result, Vehicle Accident Analysis & Reconstruction Methods remains the definitive resource in accident reconstruction.

Seat belt syndrome: a case report

Seat belt syndrome happens when a car meets an accident and person sitting in the car with seat belt on gets abdominal injuries typically, seat belt mark with intestinal injuries and factures of ribs and lumber spine. The abdominal injuries are usually intestinal perforations. Doctor seeing the motor vehicle accident must keep in mind seat belt syndrome while examining. As the traffic rules are getting enforced strictly in developing countries we are seeing seat belt syndrome cases in these countries more and more. We presented here a case of seat belt syndrome in 35 years old women.

Double-level noncontiguous thoracic Chance fractures treated with percutaneous stabilization: illustrative case

BACKGROUND Chance fractures are unstable due to horizontal extension of the injury, disrupting all three columns of the vertebra. Since being first described in 1948, Chance fractures have been commonly found at a single level near the thoracolumbar junction. Noncontiguous double-level Chance fractures that result from a single traumatic event are rarely reported in the literature. OBSERVATIONS The authors report a case of an 18-year-old male who presented to the emergency department after a rollover motor vehicle accident. The patient complained of severe back pain when at rest and had no neurological deficits. Computed tomography revealed two unstable Chance fractures of bony subtype located at T6 and T11. The patient underwent percutaneous stabilization from T4 to T12. The postoperative assessment revealed continued 5/5 power bilaterally in all extremities, back pain, and the ability to ambulate with a walker. At 3 months after the operation, clinical assessment revealed no significant back pain and the ability to walk independently. Imaging confirmed stable fixation of the spine with no acute osseous or hardware complications. LESSONS This report complements previous studies demonstrating support for more extensive stabilization for such unique fractures. Additionally, rapid radiological imaging is needed to identify the full injury and lead patients to appropriate treatment.

Incidental appendicitis in a blunt trauma patient: a case report

Acute appendicitis is a relatively common disease, but it is rarely caused by trauma. There are some reports on appendicitis caused by blunt abdominal trauma, but the pathophysiology is still uncertain. In this report, we presented a case of a patient who developed acute appendicitis following blunt trauma to the abdomen sustained during a motor vehicle accident.

An Unexpected Finding of Hepatosplenomegaly in a Pediatric Patient

Gaucher disease (GD) is a rare autosomal recessive metabolic disorder. It is characterized by a deficiency of lysosomal glucocerebrosidase, which results in the accumulation of glycosphingolipid substrates, primarily glucosylceramide, in the phagocyte system. In GD Type 1, the liver, spleen, and bone marrow are typically affected. We report the case of a 7-year-old female with GD Type 1 who presented with hepatosplenomegaly detected incidentally following a motor vehicle accident. She was found to have concomitant thrombocytopenia and Erlenmeyer flask deformities of her lower limbs. Diagnosis was made on the basis of very low leukocyte β-glucocerebrosidase activity and elevated plasma chitotriosidase. DNA mutation studies revealed both c.1226A>G and c.116_1505 deletion (exons 3-11). The patient is currently managed with biweekly intravenous imiglucerase (Cerezyme) replacement therapy. She demonstrated resolution of thrombocytopenia and hepatosplenomegaly at 2-year follow-up. Physicians must consider this rare diagnosis in children presenting with hepatosplenomegaly to prompt timely management.

Blunt traumatic aortic injury: CT angiography images and short review of current literature

Blunt traumatic aortic injury in high-energy motor vehicle accidents is a rare but life-threatening condition. Proper treatment after prompt and accurate diagnosis is critical to reduce the death rate. The purpose of this article was to highlight the points to be considered in blunt traumatic aortic injury due to high-energy motor vehicle accident.
